Week 2 of the fantasy season proved one undeniable truth: It's very hard to predict what is going to happen with NFL players from week to week. All fantasy players can do is look for trends and favorable matchups and make their best guess at the best play.

And then hope and pray.

Here's look at the Week 2 Stock Watch:

Stock Up:

Matt Schaub (QB, Hou) - After a horrible Week 1, the Texans signal caller came roaring back in the season's second week to post outstanding numbers. With WR Kevin Walter looking like he'll be back in Week 3, Schaub is looking good.

Jay Cutler (QB, Chi) - I'm never going to be a Cutler fan, but he did put up a great week against the defending Super Bowl champions. He picked up 236 yards and 2 TDs and 0 interceptions, which is a solid number for a QB with not-too-stellar receivers.

Cedric Benson (RB, Cinc) - This is the guy we've been waiting for since Benson starred at Texas. He is running strong behind a surprisingly good OL and QB Carson Palmer looks health. That all adds up nicely for Benson and the Bengals.

Chris Johnson (RB, Tenn) - Has Johnson quit gaining yards yet?? That was just a little ridiculous on Sunday. Keep him in the lineup.

Reggie Bush (RB, NO) - He actually scored a rushing TD last week (after having a TD called back in Week 1) and Mike Bell is hurting. With Pierre Thomas still unreliable, Bush is looking good in that Saints offense.

Donald Driver (WR, GB) - Driver is clicking with Aaron Rodgers, catching 6 passes (out of 9 targets) for 99 yards. He might have become a possession receiver as a vet, but he looks to be a favorite of his QB.

Marques Colston (WR, NO) - Colston torched the Eagles for two scores and 98 yards and his QB is the best in the game right now. His stock can't get much higher.

DeSean Jackson (WR, Phil) - We were worried about Jackson with McNabb out, but Kevin Kolb proved he can throw and Jackson showed once again that he can run. He's a candidate for a big play every week.

Tony Romo (QB, Dal) - You can't cut him because he will give you games like Week 1 and carry you to a win. But Romo is still too careless with the ball and he'll hurt you, too. Welcome to fantasy football.

Brady Quinn (QB, Clev) - If he is your starting QB, you are probably not going to win many games. Quinn just isn't very good right now.

Brian Westbrook (RB, Phil) - I'm officially worried about Westbrook now. He doesn't seem to have the same quickness and break-away ability. Be wary, though he could breakout any week.

Darren McFadden (RB, Oak) - The Raiders are just horrible and McFadden doesn't help. He came out of college with a lot of hype, but he's yet to prove he is anything more than a backup in fantasy.

Greg Jennings (WR, GB) - I had Jennings as a top 5 receiver going into this season. He better pick it up or he won't make the season-ending top 50.

Santana Moss (WR, Was) - It is getting more and more ugly for Moss. He had 6 targets in Week 2 and only 3 receptions. If you drafted him very high, you are very sorry.

Lance Moore (WR, NO) - Quite simply, there are just too many targets in New Orleans right now and Moore has been slow to get into the act. He needs to pick it up quickly or he should be headed to the fantasy waiver wire.
